Hello
We have recently moved our computers from Windows NT to Windows 7, and at the same time we've upgraded from ArcGIS 10.1 to 10.2.
I have an ArcGIS extension created in Visual Basic 2010, which had been running well in the previous set up. I have moved things over onto my new computer in this new environment, and now something is not working.
I have on some of my forms a click event which access one of the tools elsewhere in the same extension. When the click event is accessed now a unhandled exception error comes up "Object reference not set to an instance of an object".
I've obviously missed, or forgotten doing something which I had previously done. Could anyone help with what that might be. Here is the offending click event ...
Private Sub cmdSelect1_Click(ByVal eventSender As System.Object, ByVal eventArgs As System.EventArgs) Handles cmdSelect1.Click
Dim pUID As ESRI.ArcGIS.esriSystem.UID = New ESRI.ArcGIS.esriSystem.UID
Dim pCommandItem As ESRI.ArcGIS.Framework.ICommandItem = Nothing
Dim Application As ESRI.ArcGIS.Framework.IApplication = m_pApp
pUID.Value = "{" & SelectFPoint.ClassId & "}"
pCommandItem = Application.Document.CommandBars.Find(pUID, False, False)
pCommandItem.Execute()
End Sub
